Clinical Trial: The Post Stroke Preventive Trial (PREVENT). A RCT Nested in a Cohort
This study is not yet open for patient recruitment.
Verified by Hvidovre University Hospital November 2005
|
Purpose
Patients with a diagnosis of stroke or TIA, who are already included in the RIALTO-cohort study are asked to participate in a RCT after discharge from hospital.
Patients in the intervention group will receive four visits by a study nurse with the aim of controlling the patient''''s hypertension, reducing risk factors like tobacco smoking and obesity, and motivating the patient to physical activity and to a healthy diet.Patients in the control group will receive the usual treatment.
This study is aimed at testing the hypothesis, that
Primary outcome: the blood pressure lowering will be greater in the intervention group Secondary outcomes: the blood pressure will be lower in the intervention group and the number of patients who have stopped smoking will be greater in the intervention group The number of obese patients who have reduced their BMI will be greater in the intervention group The number of patients with a Rankin Scale<3 who are physically active for four hours a week will be greater in the intervention group Time to recurrent stroke, MI and death will be longer in the intervention group
Outcomes are measured by follow up visit one and two years after inclusion in the study
Expected Total Enrollment: 342 in the RCT, 1200 in the cohort
Study Start: 011205 (PREVENT) Study Completion: January 2009(PREVENT), June 2013 (RIALTO Cohort study)

Official Title: The Post Stroke Preventive Trial (PREVENT) A Randomised Controlled Trial Nested in a Cohort (RIALTO)
Secondary Outcomes: blood pressure; BMI; Smoking status; Level of physical activity; Time to events:Stroke reccurrence, MI and death; all assessed 12 and 24 months after inclusion in the study
Expected Total Enrollment: 342
Study start: December 2005; Expected completion: October 2009
Last follow-up: December 2008; Data entry closure: January 2009
Stroke survivors are at risk of cerebrovascular and cardiovascular complications. In Denmark 25% of stroke admissions are caused by recurrent stroke or TIA. Little is known of the risk factors for recurrent stroke. This is being investigated in a cohort study (RIALTO) inititated in may 2004. The PREVENT study is aimed at studying the health behavior of stroke survivors as well as the effect of a preventive intervention aimed at risk factors associated with hypertension. Hypertension is the main risk factor for primary stroke and the one risk factor known to be associated with stroke recurrence.
Inclusion criteria: inclusion in the RIALTO-cohort, no severe cognitive deficits or dementia, no other life threatening disease.
Exclusion criteria: discharge to a nursing home
Participants (n=342) are randomised to either the intervention group (n=171) or the control group (n=171). Randomisation is performed by a computer-generated allocation schedule, with the randomisation sequence blocked from previewing. The analyser will be blinded from the allocation of the patients.
Baselinedata: Blood pressure, BMI and Rankin scale will be monitored few days prior to discharge.Blood pressure will be measured according to standards set by the Danish Society of hypertension.
Patients in the intervention group will receive a visit by a study nurse one, four, seven, and ten months after discharge. The aim of the visits are: controlling the patient''''s hypertension, reducing risk factors like tobacco smoking and obesity, motivating the patient to physical activity and to a healthy diet as well as compliance with pharmacological treatment of hypertension, diabetes, hypercholesterolemia and anti-thrombotic treatment.Patients in the control group will receive the usual treatment.
This study is aimed at testing the hypothesis, that
Primary outcome: the blood pressure lowering will be greater in the intervention group Secondary outcomes: the blood pressure will be lower in the intervention group and the number of patients who have stopped smoking will be greater in the intervention group The number of obese patients who have reduced their BMI will be greater in the intervention group The number of patients with a Rankin Scale<3 who are physically active for four hours a week will be greater in the intervention group Time to recurrent stroke, MI and death will be longer in the intervention group
Outcomes are measured by follow up visit one and two years after inclusion in the study. Hypertension is defined as a blood pressure > 140 mm Hg or > 90 mm Hg. The diagnosis of a recurrent stroke will be based on a CT og MR scan or on the clinical diagnosis made by a neurologist.MI should be confirmed by an ECG and by relevant biomarkers.
All participants will be followed up by register data for six years from inclusion as will all participants of the RIALTO cohort.
